Abstract: A machining system for electromachining a workpiece that in one embodiment includes a machine tool, a cutting tool for performing the eletromachining, and a tool holding apparatus for conductively holding the cutting tool and coupled to the machine tool. The tool holding apparatus includes a holding element for holding the cutting tool and at least one solution releasing element. The solution releasing element is used to receive machining solution and release the machining solution onto a predetermined area of the cutting tool through at least one group of channels. Each group of channels includes at least two channels configured to respectively release the machining solution onto at least two adjacent sections in the predetermined area of the cutting tool.
